What kind of vector is in the template? 1:N #102

Closed LionLion888 closed 9 months ago

LionLion888 commented 1 year ago

Hi there,

When createTemplate(TemplateRole=Enrollment_1N), the implementation will return a template to the calling application.

I am wondering to know what kind of vector is in the template? Is it a feature from the face detection or it can be a similarity score produce by the face recognition as well.

Besides, if the vector in the template can be a similarity score, does that mean the Template Generation will deal with face detection and face recognition, also the total of the face detection and face recognition execution time need to within 1.5 sec.

createTemplate produces feature data from one image. The function takes one image, so there is nothing to match against, so there is no recognition, no similarity score.
